THE GOVERNOR

The governor controls the speed of the engine and is of the ball type. When the engine runs above its regular speed, the balls on the governor widen their circuit, which presses in on the pin going through the governor spindle. This forces the detent blade in so that it catches behind the block on the cam rod and holds the exhaust valve open, at the same time stopping the spark and cutting off the supply of fuel, until the speed of the engine is reduced to where it should be, then the detent blade flies out again, releasing the cam rod and the engine takes up its regular operations. When running empty the engine exhausts every eight to ten revolutions' of the flywheel.

HOW TO ADJUST THE DETENT BLADE

When the exhaust valve is wide open and the detent blade is pushed in behind the catch block on the cam rod, there should he only the thickness of a postal card between them. When adjusting the detent blade, the speed lever should be set at lowest speed and the detent blade should stand about 1/16 inch away from the catch block.

To adjust the detent blade loosen the locknut "No. 077" and screw the adjusting screw "052" either in or out, until you have the blade where it should be, then tighten the locknut. See page 34.

THE DETENT CATCH BLOCK

The catch block on the cam rod is made of tool steel and should last a long time. If the block should wear on one side so it does not hold the detent blade properly file off the point of screw where it is riveted on side of rod next to the engine, remove the screw with a screwdriver and turn the catch block around, using the other side. After both sides of the block are worn, it will be necessary to replace same with a new one. (See No. 054 in list of repairs, page 26.)

TO STOP THE ENGINE

First. Shut off the gasoline by closing the fuel valve.

Second. In cold weather drain the water from the reservoir by opening the drain cock underneath the cylinder, also remove plug from bottom of cylinder head. Be sure to do this, as even a light frost may crack the cylinder or cylinder head by freezing the water.
